Let Psi(x,t) denote the solution to the Schrodinger equation for a single
particle in a square well. We consider times series generated by A(t) =
Psi(x,t) for fixed values of x and varying values of t, and show that
these time series exhibit biotic behaviour. Bios has many properties of
chaos with further properties in common with natural time series such as
heartbeat intervals and with mathematical recursions such as x(t+1) = x(t) +
g sin(x(t)) for sufficiently large values of g. The significance of
this last process equation is that it embodies characteristics associated
with a combination of positive and negative feedback. The talk will discuss
the physical background to this work, the method of verification for
these biotic properties and the context of bios, time series and quantum
chaos.
